PROBLEM TO BE SOLVED: To provide a fuel tank with a canister integrated therewith and having an excellent air distribution property and the sealing performance of port fitting parts of an atmosphere opening port and a discharge purge port. SOLUTION: The fuel tank 1 is integrally constituted by welding circumferential joining edges of an upper shell 10 and a lower shell 20 which are formed separately. In a canister 30, a side wall 31 is integrally hung from the outer wall of the upper shell. A bottom wall 33 is formed separate from the upper shell, and the bottom wall 33 is fixed to the fore end of the side wall 31. An atmosphere opening port fixing part 40 and a purge port fixing part 50 are formed at an upper wall 37. In the atmosphere opening port fixing part and the purge port fixing part, port fixing part side walls 41, 51 extend downwardly so as to form port fixing part spaces 43, 53 from the upper wall, and filters 44, 54 for partitioning the port fixing part space from a fuel vapor absorbing member 35 of the canister are fixed to fore ends of the port fixing part side walls 41, 51.
